Conveyor lining. Lining of drums of belt conveyors. Methods for rubberizing conveyor drums

As we understand it, drums are made by welding steel or by casting cast iron. You can notice that the drums remind us of a smooth cylindrical shape along the rim. In order to use the drum at its maximum value, the tape is pulled tightly against it. In order for the drum to clean itself, you need to increase the wrapping angle of the tape, and use longitudinal linings.

Linings are installed very easily, using special adhesives. To reduce slipping and movement of the belt, lining plates are used. To increase the production rate and to reduce the likelihood of cargo entering the drum plane, lining plates are also used. To increase the tenacity of the belt with the drum, a corrugated surface of the drum is used, while reducing the tension of the belt. If these rules are followed, the service life of tapes and connectors increases significantly.

  • At rubber lining The service life is long.

  • When lining with polyanite it is characterized by resistance to chemical influences, high temperatures and high humidity.

  • Polymer lining based on wear resistance, strength and protection from salts, acids and alkalis.

  • Metal lining resistant to various types of corrosion and other external factors.

Drum lining algorithm:

1) The surface is thoroughly polished, specially with a grinding machine at a depth of no more than 30 microns. The next step is to clean the surface from oils and fats using anti-grease agents.

2) A special primer is applied to the surface of the drum, the exposure time of which depends on the type of primer.

3) Apply special glue for lining and rubberizing the surface.

Lining is a method of treating a surface to make it resistant to mechanical damage or to influence chemical substances And physical phenomena(temperature).

Essentially, this is a way to strengthen the surface. Most often, parts of heavy industry mechanisms (mining, metallurgy, heavy engineering and the like) that are susceptible to constant friction succumb to it. This treatment enhances their wear resistance to mechanical abrasion, thereby extending the service life of the mechanisms.

Lining belt conveyors and their drive drums is rubberized. That is, on work surface special plates (linings) made of rubber or rubberized with ceramic inserts are applied.

They not only increase the service life of the conveyor drum, but also improve its movement, adhesion to running surfaces and prevent the belt itself from coming off the conveyor.

Drum lining methods and steps

Lining belt drums carried out by three main methods: hot or cold vulcanization, and mechanically. Depending on the method of their application, manufacturers produce different models.

The process of applying lining plates occurs in several stages. First, the surface is sanded or blasted, this is done to give it roughness. Then a layer of primer is applied, and after that a layer of glue, which will hold the pad itself. Thanks to all these procedures, the pad is securely attached to the drum.

Polymer coatings for lining

The Russian company TD Plastics Group is engaged in the design and production of various coatings, including linings for most belt sliding mechanisms. Produced polymer coatings- these are fundamentally new materials that replaced their predecessors - metal protective coatings.

They do not require such careful maintenance, but they last much longer. The product catalog from TD Plastics Group contains a wide range of materials for many areas of production: woodworking, mining and oil production, electrical installations, instrument making, water treatment, and the military-industrial complex.

In addition to finished products, it is possible to manufacture them according to special drawings with preliminary development by the company’s specialists.

Lining services from the Flisbant company

The company's qualified specialists perform fast and high-quality lining of conveyor drums not only on their own premises, but also on the customer's premises.

The fact that we have a large stock range of high-quality lining materials, including German primers and special ones, is in favor of contacting Fliesbant. adhesive compositions, which allows minimizing downtime of conveyor equipment.

Main lining process drive drum belt conveyor, the equipment manufacturer, as a rule, carries out it independently, using special technology cold vulcanization by means of which, smooth surface The drum is covered with especially durable or “lining” rubber, which may contain ceramic inclusions. On this moment, this method is the most optimal. The lining of the drums of belt conveyors effectively prevents possible slippage of the drive drum that occurs when the proper level of load on the conveyor belt is exceeded.

In some types of conveyor devices, drive drums are installed, the surface of which remains completely smooth after lining; in some, there are patterns on the lined coating, which, by the way, are a kind of business card manufacturer. However, such a pattern is not intended to perform an aesthetic function at all, but a completely utilitarian one; it allows the drive drum to self-clean, which ultimately provides its surface with better adhesion to the conveyor belt. By the way, ceramic inclusions, in turn, increase the wear resistance of the rubber coating of the drive drum, that is, the lining itself.

How to line the drive drums of belt conveyors

So, lining is the application of a protective layer to the surface of the drums driving the conveyor belt. Rubber is mainly used for lining; however, at the request of the customer, the manufacturer of the conveyor belt can apply any protective material that meets the requirements of the specific production and operation of the conveyor. As options for replacing rubber, silicone, acrylic, polyurethane, and so on can be used, and the protective layer in such cases is simply glued to the surface of the drive drum.

Advantages of lining:

  • Self-cleaning of drive drums of belt conveyors;
  • Improving traction and eliminating slippage;
  • Elimination of accumulation of moisture and dirt;
  • Stable belt tension and set speed;
  • Increasing the service life of the drive drum, conveyor belt and all equipment in general;
  • Reliable protection metal drum from rust;
  • Protection of the drum and belt from mechanical influences.

Belt conveyor drum lining technology

It should be noted that a grooved lining, that is, having either a pattern or ceramic inserts, provides more high level adhesion of the surface of the drive drum and the conveyor belt, as well as best indicator traction factor, which eliminates excessive tension of the conveyor belt, thereby extending its service life.

The lining process does not take much time from the manufacturer; the application of any material as a protective layer on the surface of the drive drum occurs quickly and efficiently. During the operation of a drum with lining, you can save time on repairs and extend the service life of the entire conveyor belt device.
